I'm back with another champion idea: Purgatio, the Savior of Good. This time it's more of a buffing and defensive support inspired by an idea in the Vayne/Background comment section. Feel free to give tons of feedback.

Abilities

Believe

Using an ability on an allied champion will increase their damage output by 5% for 4 seconds. This does not stack.

Soul Capture

RANGE: 575

COST: 50 / 60 / 70 / 80 / 90 mana

COOLDOWN: 6

Passive: When an allied unit (including himself) kills an enemy unit they will be healed for 1% of the dying unit's maximum health. This heal cannot exceed 100 hp and does not apply Believe. (1000 unit range)

Magic Damage: 60 / 80 / 100 / 120 / 140 (+ 30% AP)

Maximum Magic Damage: 120 / 160 / 200 / 240 / 280 (+ 60% AP)

Damage increase per extra soul: 20%

Active: Purgatio captures the souls of dying allied units and stores them. At 5 stacks he can activate this ability to unleash the souls. The souls seek vengeance and damage a target enemy champion based on how many souls Purgatio has stacked and slowing them by 40%. This number cannot exceed 10 stacks which will double the damage.
